Power exercises for elderly – part 1
The percentage of the population of elderly people is constantly increasing. In 2000, those over 65 were more than 400 million worldwide and is estimated to increase 1,5 billion in 2050. Of these, a percentage of 25% is estimated to be over 80 years old.
Aging influences on the reduction of many physical abilities (e.g. balance, endurance, strength, etc.) related to the control of posture. At the same time, we know that strength, which is an important factor for functional abilities declines with age, and can grow to such an extent that an elderly person cannot cope with simple everyday activities such as housework, to pull up a chair, and even throw the garbage out. The reduced functional capacity may even lead to the need for nursing home.
It is important as a person ages, to retain their strength at a level because it becomes vital for health, functional abilities and the ability to live without assistance. It is therefore a common assumption that requires care and finding methods to improve the quality of life of this population group.
Aging is responsible for a number of physiological changes in the human body which comprises reduction of aerobic capacity and has a distinctive effect on skeletal muscle with decreasing in muscle mass, strength and rate of contraction. Reduction of mixed muscle protein in 4-5% rate is observed per decade and decline of 3% in muscle mass after the fourth decade of life.
In the neural tissue is observed loss of motor neurons in the spinal cord and the brain, reducing the stimulus conduction velocity, changes in neuromuscular synapses, segmental demyelination of motor neurons and reduction in the number of motor units to increase in size.
It depends from primary factors (genetic), which cannot be affected, nor even fully understood by secondary factors (environment, exercise, nutrition, etc.). In secondary factors are intervening all health care professionals, and among them physiotherapists.
